Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a laser treatment system with mutually cooperated multiple lasers.
Background
Prostate Hyperplasia (BPH) is a common disorder in older men, accounting for about 40% of the population of men over 50 years old, up to 75% over 70 years old, and with the exacerbation of the condition, patients develop various complications of lower urinary tract obstruction, requiring surgical treatment at this time.
Since most patients with BPH are elderly patients, the patients are characterized by more systemic complications and high surgical risk besides the symptoms of urinary tract obstruction, and thus the active treatment of various complications in the surgical period is particularly important. Traditional TURP (transurethral prostatectomy) is a gold standard for the surgical treatment of prostatic hyperplasia, but in the application of traditional TURP, tissue hemorrhage needs to be treated in a large amount of time, so that the operation of increasing the visual field definition for reducing the hemorrhage in the operation greatly prolongs the operation time and increases the operation risk of the elderly and high-risk patients; in addition, since there are many residual glands in the conventional transurethral prostatectomy, the long-term recurrence rate is high, and thus a therapeutic method with lower risk and better effect is required.
At present, a laser therapeutic apparatus can be divided into a plurality of types according to laser types, and different types of lasers have different performances and effects, wherein holmium lasers take Yttrium Aluminum Garnet (YAG) as an activation medium, and laser crystals (Cr: tm: ho: YAG) made of sensitized ion chromium (Cr), energy-transfer ion thulium (Tm) and activated ion holmium (Ho) are doped to produce laser with the wavelength of 2100nm at the absorption peak value of water, so that laser energy can be efficiently absorbed by water in tissues, and the operation time is greatly shortened; the holmium laser is a high-energy pulse solid laser, the laser pulse time is 0.25ms and is far less than the heat conduction time (1 ms) of tissues, so the heat damage to surrounding tissues is very small, the holmium laser has the characteristics of safety and reliability, and the holmium laser enucleation surgery of the transurethral prostate makes the surgical treatment of BPH take a new step.
However, the haemostasis effect is still not ideal because the haemoglobin absorption of holmium laser is relatively poor, and the haemostasis problem is perfectly solved. While the red laser wavelength is 480 nm, which provides the highest combined absorption of water and hemoglobin, the laser wavelength determines the extent to which it is absorbed by water and hemoglobin, resulting in a very good hemostatic function.
Therefore, if the two lasers can be used for surgical treatment at the same time and can be switched at will, the surgical efficiency and the surgical safety can be greatly improved, and in view of the above, we propose a laser treatment system with multiple lasers cooperating with each other.
